How do you calculate a tip and split the bill?
The basic tip calculation multiplies the bill amount by the selected percentage. The calculator then adds an optional fixed service fee and divides the final total equally among the number of people.
Quick example
On a $120 bill, an 18% tip is $21.60. With no extra service fee, the final total is $141.60; split four ways, the exact amount per person is $35.40. Changing the currency only changes display formatting, not the arithmetic.
Is a service charge the same as a tip?
Not always. A restaurant-added service charge or gratuity may be different from an optional tip. In this calculator the tip percentage applies only to the bill amount; the optional service-fee field is added afterward as a fixed amount. Check the receipt to avoid adding the same charge twice.
What does per-person rounding do?
The round-up option moves each person's exact share up to the selected increment. That can make the amount collected slightly larger than the true total, so the calculator shows the extra amount created by rounding. Leave rounding off when an exact split matters.
Tip presets are shortcuts, not recommendations
Tipping customs vary by country, venue and service type. Preset percentages are only arithmetic shortcuts and do not imply that any particular rate is required or appropriate. For other percentage scenarios, use the Percentage Calculator.
